Material Choices and Colors

The most common panel roof material by far is metal: steel, aluminum, copper or stainless steel. Aluminum and steel roofs need to be painted or have a coating applied (galvanized) to protect them from corrosion. Painted roof panels can be had in a rainbow of colors to complement the structure they are protecting, and they can add some great architectural style. Copper and stainless steel do not need anti-corrosion coatings due to their natural resistance, but these materials are very expensive.
